- Description:
- Ensuring adequate water quality is essential for human health and for effective allocation of resources in agriculture, energy, and manufacturing. However, the current state-of-the-art for water quality testing requires expensive equipment and technical expertise to analyze samples and takes days to obtain results from off-site labs, making it inaccessible to...

- Description:
- Quantum dots (QDs) are promising photocatalysts due to their large extinction coefficient, large surface area-to-volume ratio, and stability upon irradiation. QDs have been studied in photocatalytic hydrogen production, CO2 reduction, and reduction of small organic molecules such as nitrobenzene. This dissertation describes the application of QDs in two photocatalytic cross-coupling...

- Description:
- Secondary organic aerosol (SOA) particles are a class of highly abundant atmospheric constituents that represent a substantial fraction of carbon within the climate system. A subset of naturally-occurring SOA particles are formed through atmospheric oxidation of biogenic volatile organic compounds (BVOCs), forming oxygenated products of lower volatility that can partition...

Risk Prediction with Longitudinal Gene Expression Data Using Statistical and Machine Learning Method
- Description:
- With the advancement of high-throughput sequencing technology, it has become much easier to extract gene expression data and to discover gene-disease associations more efficiently. Longitudinal gene expression data offer more insight into expression patterns for distinct patient groups compared to cross-sectional data. For instance, patients diagnosed with subclinical acute rejections...
